Technical and Economic Assessments of sCO2 Power Cycles for Fossil Energy Applications
- NETL
NETL’s techno-economic analyses in both direct and indirect sCO2 power cycles are presented. Four major preliminary techno-economic analyses have been completed for commercial-scale sCO2 plants: an indirect sCO2 plant with an oxy-coal circulating fluidized bed (CFB) heater and carbon capture and storage (CCS), an indirect sCO2 plant without CCS using an air-fired coal CFB, a coal gasification unit integrated with a direct sCO2 plant, and a natural gas-fueled direct sCO2 cycle. Detailed focus area studies designed to improve upon the cost of electricity of the sCO2 plants in these preliminary techno-economic analyses are reviewed, which include: an sCO2 component cost scaling study, a cooling system integration study, a primary heater integration study for indirect sCO2 applications, air separation unit modeling for direct sCO2 cycle integration, design and modeling of a commercial-scale cooled direct sCO2 turbine, and direct sCO2 integration with alternative coal gasifiers.
